Normal cautions should be sufficient to manage the small, thin wind slabs lingering around higher elevations. Pray for snow!

Confidence

High

Avalanche Summary

Only thin, small wind slabs were reported after a skiff of new snow and a round of ski cutting in the Castle area on Monday.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

A few cm of recent snow has been getting blown around on top of a crust that exists to 2000 m as a result of warming on the weekend. Above this elevation it blends into heavily wind-affected snow, with some thin new wind slabs scattered around exposed terrain. Forecast trace flurries will do little to change this picture over the next few days.

The mid-pack continues to settle and consolidate. Basal facets are found in the bottom 20-40 cm.
